Science made us big, helped us escape the struggle of nature, build us strongholds of civilization, extended our physical limits, freed us from diseases and provided us with the tools to do anything we want. Always remember that and the principles of science. Take nothing for granted, seek new knowledge, falsify, validate, reevaluate your hypothesis according to new data, take problems as challenges and never stop learning.
And don't forget about the eco-system. Remember cybernetics, we are influencing the world and the world is influencing us. If you want to live in an healthy environment, treat your surrounding accordingly. That is, of course, true for every relationship.
